Abstract:

采用热重-质谱(TG-MS)研究了两种不同粒径(230μm,40μm)HNIW的热分解过程,并对230μm的HNIW等温热分解残余物进行红外、元素分析研究。结果表明:230μm的HNIW的非等温热分解分为两个阶段,40μm的HNIW的非等温热分解只有一个快速分解阶段,气体产物主要为NO、N2O和CO2,还有少量的NO2,C2N2H2。230μm的HNIW的204℃等温热分解产物和非等温热分解第一阶段的相同。230μm的HNIW204℃等温热分解10min、60min的残余物的平均分子式分别为:C3H4.5N5.5O和C2H4N2O,HNIW204℃等温热分解反应可写为:C6H6N12O12=6NO+N2O+2CO2+2HCN+C2H4N2O。
